Review

Hello! I saw your board broke, but from what you have had time to answer, it looks good. There are some unanswered questions you could still work on even without a board, like in bare7_3 Validation:

Explain in your own words the purpose of:

    602: fa02 f000    	lsl.w	r0, r2, r0
    606: 6008         	str	r0, [r1]

Hope you get a new board soon!
